compensated or presents a compensation deviation will result in the measuring error
or mistake. For adjusting the probe compensation, please carry out the following
steps:
1. Set the attenuation coefficient of the probe on the menu as 10X and that of the
switch in the probe as 10X (see "How to Set the Probe Attenuation Coefficient"
on P12), and connect the probe with the CH1 channel. If a probe hook tip is used,
ensure that it keeps in close touch with the probe. Connect the probe tip with the
signal connector of the probe compensator and connect the reference wire clamp
with the ground wire connector of the probe connector, and then push the
Autoset button on the front panel.
2. Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Figure 3-6 and Figure 3-7).

How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
To change or check the probe attenuation coefficient on the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 - CH4 button).
(2) Select Probe in the bottom menu; select Attenu in the right menu, turn the M
rotary control to select the proper value corresponding to the probe.
This setting will be valid all the time before it is changed again.
